UNITED STATES JAMES J. HENNESSY, OF NEW YORK, N. Y.

JOURNAL LUBRICATOR.

Application filed September 20, 1921.

To all whom it may concern:

Be it known that I, JAMES J. HENNnssY, a citizen of the United States,residing at city of New York, State of New York, have invented a certainnew and useful Improve ment in Journal Lubricat'ors, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, forming part ofthis specification.

My invention relates to journal lubricators such as are used on railwayrolling stock, and consists in an improved lubricant reservoir andpumping mechanism.

In copending applications filed by me, Serial Number 397,3 l1, andSerial Number 397,342 I show somewhat similar reservoir and pumpingmechanisms in which the pump plunger is actuated in one direction bypositive engagement of an operating rod by a journal or wheel elementand is actuated in the opposite direction by the energy of a compressedspring.

The main object of my present invention is to eliminate the use of aspring for the purpose mentioned, and to provide a positive actuation ofthe operating rod in both directions.

In the accompanying drawings, which illustrate a selected embodiment ofmy invention,

Figure 1 is a longitudinal section through my lubricator as mounted uponthe journal of a railway car.

Figure 2 is a transverse vertical section on line 22 of Figure 1.

The lower portion of the reservoir 1 forms an oil well and the upperportion of same seats a waste pan 2 adapted to hold the usual cottonwaste against the journal and, away from the pump mechanism. The pumpcyl inder is indicated at 3 and is provided with the usual plunger 4which is designed to re ciprocate in a horizontal direction. Extendingthrough the reservoir from end to end and projecting beyond the endwalls thereof is a contact rod 5 which is connected to plunger 4 bymeans of alever 6 and a stud 7, the lever being fulcrumed to the bottomof the reservoir at 8.

Cylinder 3 terminates near the center of.

Specification of Letters Patent.

Patented July 25, 1922.

Serial No. 501,868.

The opposite end of rod 5 is adapted to be engaged by the side of a hub13 of the wheel mounted on journal A.

It is well known that in the travel of railway rolling stock, ,there isa constant shifting back and forth between the journal and the journalbox, and I rely upon this shifting to operate the pump by alternatecontact of the hub B and collar 12- with the respective ends of rod 5.This is a positive operation which does not depend for its functioningupon a spring such as has hitherto been used and which is subject to thepossibility of being broken or being clogged with dirt or other foreignmatter.

While I have shown rod 5 of a length somewhat less than the distancebetween collar 18 and hub B, this is a preferred arrangement notessential, as the collar 13 may be positioned right against the adjacentend of rod 5.

I contemplate this and such other changes as are likely to be suggestedin the commercial development of my devices, without any departure fromthe spirit of my invention, as set forth in the following claim.

' I claim:

In combination with the journal and hub of a car wheel, a collar adaptedto be clamped to said journal at a point spaced from the wheel hub, ajournal lubricator applied to said journal between the wheel hub andsaid collar, said lubricator comprlslng a lubricant reservoir and a pumpfor feeding lubricant from said reservoir to the jo urnal, a pumpoperating rod extending through the opposite walls of said lubricatorwith its opposite ends respectively oppos ng the wheel hub and collar,and a connectlon between said rod and said pump.

In testimony whereof I hereunto afiix my signature this 29th day ofJune, 1921.

JAMES J. HENNESSY.
